Industrial expansion and suburban growth define this mid-1970s landscape, where the massive Steel Plant northwest of Fontana serves as a major regional anchor. The map reveals a corridor of activity stretching along the San Bernardino Freeway and Foothill Blvd, with pink-shaded revisions highlighting significant urban development around Bloomington and Rialto. To the south, the Jurupa Mountains and Mount Jurupa create a natural barrier, while the Santa Ana River marks the southern border near Rubidoux. Evidence of the area's extractive economy is visible in the numerous excavations, including the Crestmore Quarry and a large Cement Plant. Genealogy researchers can find many local landmarks such as Green Acres Memorial Gardens Cem and several schools ranging from Eisenhower High Sch to Jurupa Hills Sch, alongside institutional hubs like the County Museum.
